Skyrme泛函中一种修正的密度依赖性的探讨
Exploration of a modified density dependence in the Skyrme functional
摘要：
一个变种的基本Skyrme-Hartree-Fock（SHF）功能被认为是处理一种新形式的密度依赖。它只使用整数幂，因此将允许投影方案（粒子数，角动量）更合理的基础。我们优化了新的功能，完全相同的调整策略，在早期的研究中使用的标准Skyrme功能。这允许直接比较新函数相对于标准函数的性能。我们讨论各种观测：有限核，核物质，巨共振，超重元素和能量系统的整体性能。新的功能执行至少以及标准的，但提供了更广泛的适用性（例如，投影）和更灵活的制度，高密度。
英文摘要：
A variant of the basic Skyrme-Hartree-Fock (SHF) functional is considered dealing with a new form of density dependence. It employs only integer powers and thus will allow a more sound basis for projection schemes (particle number, angular momentum). We optimize the new functional with exactly the same adjustment strategy as used in an earlier study with a standard Skyrme functional. This allows direct comparisons of the performance of the new functional relative to the standard one. We discuss various observables: bulk properties of finite nuclei, nuclear matter, giant resonances, super-heavy elements, and energy systematics. The new functional performs at least as well as the standard one, but offers a wider range of applicability (e.g. for projection) and more flexibility in the regime of high densities.
